LED Faucet Light

In the future, people that don't place LEDs everywhere will be shunned by civilized society. Children will ask their parents to tell them what it was like having to live before LED toilet seats and blue LED faucet lights, like this one.

This particular life-improving gadget attaches to your bathroom faucet with its included universal adapter and is activated as the water flows through. Once the LEDs are on, the water glows space-age blue. The unit happens to be watch-battery powered, but wouldn't it be cool if it were powered by generating electricity from the water passing through it - would that be even possible or is the gadget simply too small to contain something like that? Anyone know?

Dave, thanks for the tip.
